Fig. 8 is a top plan thereof;

Fig. 9 is a section `on the line 9--9 of Fia- -7, l

Fig. 1() is a section on\ the line 10-10 of Fig. 7, and

Fig, 11 is a separated perspective to illustrate the method of joining' the scraper to its'operating shaft. l

The disher has a vsubstantially hemispherical metal bowl 15 within which a curved scraper 16 is adapted to move so as to free the ice cream therefrom. The bowl is rigidly securedto a handle which includes a supporting frame-section 17-and a handgrip-section 18. Scraper 16 ismoved .by the. operator manipulating an operating lever 19. i l

Supporting frame 17 is formed somewhat in the shape of an elongated U or hairpin having two substantially parallel legsv 20 and 21 vinterconnected at their rear ends by a yoke or base 22. The forward ends of legs 20 and 21 extend outwardly and are curved to form feet 23 and 24 respectively. These feet embrace portions of the bowl adjacent its rim and may be secured thereto by suitable means such as solder, re-enforced if desired by rivets or spot welds-25. The entire supporting frame ,may be formed from a single piece of sheet metal stamped and bent to the desired shape; This type of construction not only provides an open and easily cleaned structure, but one which is 4inexpensively produced, platedI and polished or, .otherwise given the desired finish. It is also-rigid and strong although of relatively light Weight.

The forward or outer end of scraper 16 has a rivet 26 secured thereto. This rivet passes loosely through a hole in bowl 15 and, being upset or headed onthe outside, provides a pivot for the outer end of the scraper and also prevents it from being removed. The inner or rear end of scraper 16 isrigidlysecured to an operating shaft 27 which passesv loosely through a hole in bowl 15 diametrically oppositethe hole for rivet 26. The bowl thus provides bearings for the scraper and the outer end of shaft 27. The rotation of shaft' 27 turns the. scraper to cut or loosen the ice cream from j near its rear end a small pinion 28 is rigidly secured thereto.l Pinion 28l is rotated by,k operating lever 19 as will be hereinafter described. By making legs 20y and 21 of the bowl supporting frame of sucient depth, their edges will project -well beyond the surface of vshaftv 27 as shown most clearly iny Fig. 2, and protect 'the same against injury. This feature is of importance because it isk common practice for operators tol strike or pound the handle of a disher upon some, solid object, such as the edge of an ice cream can, while cleaning the same'or freeing it from excess ice cream. Consequently if the shaft is exposed, it may; become bent or otherwise damaged when vsubjected to such treatment and the ease ofY operation may be greatly impaired. l

lso, since the greater dimensions ofthe 31 lies infront of frame legs are in the direction 'of the maximum strains during t-he dishiir'g operaftions, these legs act like channel irons to tvithstand the forces vwhich tend to bend and buckle them. i

Operating lever 19 isformed substantially in the shape of a triangle, the base df which is closed by a curved rack Y29. The teeth of rack 29 mesh With the teeth of pinion 28. Near its apex lever 19 is provided with a projecting boss or bearing luo through whicha screvv 30 passes to pivotaily attach the lever to a bracket 31. Bracket 31 is rigidly securedA to and projects at substantially a `right angle from the handle. The edge of lever 19 is bent to form a flange 32 which constitutesa housing for a biasing spring 33. One vend of liange 32 is extended beyond 'rack 29 to form alug 34 which engages leg 21 to limit the movement of the operating lever in one direction. The other end of flange 32 is extended and broadened 'out to form a thumb piece 35 by means of which the operator may actuate the lever with the thumb of the hand the1 grip of the disher.l engaging leg 20, limits the movement of lever 19 in the reverse direction.

grasping Spring 33 has its central portion bent into p a loop to encircle the bearing lug of lever of a relatively The lever may 19, one of its legs 36 lying Withiny and against flange 32. The other leg 37 of spring 33 abuts the inside of frame leg 21 as most clearly shown in Figs. 2 and 5. Thu-s the actuation of lever 19 in one direction to the right as viewediin Figs. 1 and 4, or to `the left as viewed in Fig. 5) serves, to tension the biasing spring so that when the operating lever 1s released the spring returnsthe operatinglever shaft and scraper to normal position. This construction permits the use lon spring and,rsince it acts mainly like a leafgspring instead of a coil spring, it will withstand 'severe service. The principal function of the loop is to hold the spring in place rather than to give the desired resiliency. f

Both the operating lever and its supporting bracket may be made of sheet metal, each stamped and ormed from a single piece.

be made in skeleton form as shown, vto reduce Weight. Stampare inexpensively made and finished. The flange of the operating levernot only provides a housing for the biasing spring and stops to limit the movement, but

l servesalso to strengthen the structure and make it less susceptible to bending under severe service and-abuse.

Lever supporting bracket 31 is ysecured to' the frame section ofy the handle b bending the same intoa loop 38 about the base or yoke 22 thereof as most clearly shown in Fig. v2. lThus the base of bracket Thumb piece 35' or open 'in vthe base block of the frame.

yoke 22, is then bent around onev edge thereof, next lies against.

the backof yoke 22 and finally is bent or crimped down upon the opposite edge thereof. The anchorage of the bracket to the vframe section may be further strengthened and made more permanent by soldering or Welding together the overlapping parts. This constructionl provides a thick, strong, and substantial seat or base block for the attachment of grip 18 as Will be` hereinafter described. The operating lever bracket also serves as a stop or abutment against which the operators hand can rest and push, espef cially when forcing the bowl into the icecream. This abutment makes it easier for the operator to force thebowl of the disher into relatively hard and solid materials such l as hard ice cream.

The'parallel relation of-the pivot of the operating lever'and the scraper driving'shaft eliminates the tendency of the lever to skew or be Warped from its normal position when underl heavy load. Such skewing or War ing .would interfere-With the proper mes 14 ing ofthe rack and 'pinion'teeth as has been found to be the case Where the lever and shaft axes are at right angles. It also makes `assembly easy.

Grip v18, which may be made of Wood or other suitable material, has a metal stud 39 rigidly imbedded in and project-ing from the front end thereof. The forward end of the stud 39 is provided with a cylindrical'recess 40 into which the rear reduced end ofvshait 27 is journaled. By externally threading the stud 39 throughout its' length, one end may be screwed into the Wooden grip to anchor the same thereto, and the other end may be screwed into a threadedholen provided in the base block formed by bracket loop 38 and frame yoke 22 so 'as to anchor 'the two sections of the handle together. Thls arrangement makes. a strong and compact rstructurebecause the shaft bearing and grip anchoring stud are telescoped and the mounting space required therefor is reduced. A metal nipple or ferrule 41`may be applied to'the end ofthe grip to protect the same` against Splitting and give it a-linished ap-v pearance. frame section ofthe handle, stud 39, which ordinarily Will be firmly imbedded in the grip, has the reduced end of shaft 27- in serted therein and is then screwed into place y The parts may beso related that F the end of 7stud 39 will co-operate with the shoulder at the enlargement of shaft 27 to prevent excessive end play of the operating shaft. The normal-thrust exerted upon the shaft by the y scraper, which ordinarily possesses considerable resiliency, will tend to keep the shoulder In assembling `the grip to the end of shaft 27 against the. end'of stud 39 and will thereby maintain the rear-end of lever 54. Scraper 51 is, provided with a" rivet 55 in its outer end which is journaledy in a hole in the bowl as previously explained. The inner end ofscraper 51 is secured to an operating shaft 56 inany desired and approved manner. v f f Frame 52- is formed from a tube of suitable material such as brass' or steel. Its forward end is enlarged and provided with a ange -57 which embraces the bowl and is secured thereto by solder, welding or rivets, as desired. The rear end of frame 52 has a substantially ,U-shaped bracket 58` rigidly attached thereto. One'leg 59 of bracket 58 is extended `.to provide a stopeor abutment forthe operatorshand and. to furnish a mounting for voperating lever 54. Operating lever 54 which -is of substantially triangular shape and provided with a curved rack 60, has 'a boss or bearing lug 61 projecting therefrom. It is formed with a flange 62 which on onev side is enlarged and ex' tended to form a thumb piece 63.` lBoss 61 extends through a hole in leg 59 so that it lforms a pivot on which the operating lever oscillates. It isheld in place by a washer 64 and a cap screw 65 which threads into its end. A biasing spring 66 encircles stud 61 and has one leg 67 lying along` and in engagement with iiange 62 of the operating 1 lever. The other leg 68 of the spring abuts a fixed post 69 which is carried by'leg 59 of bracket 58. 4Thusl the movement of the operating lever in one direction by the operator tensions the biasing spring so that it will return the level' when the same is released. Post 69 extends through a curved slot 70 inthe face of operating lever 54 and thus also serves as a stop for 'limiting the movement 'of the operating lever.

A pinion 71`is rigidly secured to the inner end of shaft 56 in a position to mesh with the teeth of rack 60. Consequentlythe movements of operating lever 54 are imparted to the shaft and scraper.

Bracket 58 has a lug o'rboss 72 projecting rearwardly therefrom. lThis boss is' internally threaded for receiving a grip holding screw 73. Grip 53 has a bore therethrough for the passage of screw 73, the forward end being enlarged to accommodate lug 72, so that'when the screw is tightened it holds the grip firmly in lace.

The modifie construction of the disher has many characteristics and structural features in common with the preferred construction. The operatingshaft and its pin ion are well protected against injury. The axes of the operating shaft and operating lever lie parallel to each other with the ad vantages which heretofore have been pointed out for such an arrangement. The `operating lever may be stam ed from sheet metal and it is adapted to ouse and'shield the biasing spring. The biasing spring is long and -of the leaf variety and possesses the merit heretofore attributed to this type of spring.

Figure 11 is a detail perspective view of an improved Vconstruction for obtaining a strong' and durable connection or joint between the scraper and its operating shaft. Heretofore considerable diiiiculty has been experienced and breakage'of the joint or of the scraper 'at or in the vicinity of the joint has beenasource of annoyance. In the lmproved construction', an enlarged .tubular ead 75 is pressed upon and secured to the end of anoperating shaft 27-56 `by solder or nother suitablemeans. The endof head 75 has slots76 cut in' its front'v face, for receiving the reduced end 77 of scraper 16'-- 51. '(1`he depth of slots 76 isv made sli htly greater than the thickness of the re uced scraper end 77 so that when end 77 is placed ,in the slots the proj eting portions 7 8 on the head may be Ariveted over to overlap `the back of the reduced end ofthe scraper to hold the same in place as most clearly shown in Figuresv 1, 2, and 6. After being thus assembled, the scraper and head may be further anchored together by suitable means,

such as solder. This construction affords a strong, rigid and durable joint. The load is not borne to any great extent vby the solder and there are no sharp'bends in the scraper so that separationand breakage isprevented.
